SOLE-PRESSING MACHINE.

Specification of Letters Patent.

Patented April '7, 1908.

To all whom it may concern:

Be it known that I, WARREN FRASIER, a citizen of the United States,residing at Lynn, in the county of Essex and State of Massachusetts,have invented certain new and useful Improvements in Sole-PressingMachines; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same,

The present invention relates to sole pressv ing machines and moreparticularly to sole pressing machines which comprise a shoe supportingjack, a cooperating sole pressing form, and means for actuating the jackand form to subject the sole of a shoe supported upon the jack to arolling pressure.

An object of the invention is to provide a rolling pressure soleleveling machine of improved construction and mode of operation by whichthe sole of a shoe can be subjected to any desired number of pressingoperations at the will of the operator in order to properly beat out orlevel the sole.

Other objects of the invention are in general to improve theconstruction and operation of rolling pressure sole leveling machines.

With these objects in view the present invention consists in theconstructions, arrangements and combinations of parts hereinafterdescribed and claimed, the advantages of which will be obvious to thoseskilled in the art, from the following description.

The invention is intended primarily as an improvement on the well-knownTripp giant leveling machine disclosed in the patent to Tripp No.296,486, April 8, 1884, but it is to be understood that certain featuresthereof are not limited to use in machines having the same generalconstruction as the machine of said patent. It is also to be understoodthat while the invention is preferably embodied in a machine providedwith two jacks and two cooperating sole pressing forms, as such amachine possesses advantages which will be readily understood by thoseskilled in the art, certain features thereof are not limited to such amachine but may be embodied in a machine provided with a single jack anda cooperating form.

The machine hereinafter specifically described embodies the variousfeatures of the invention in the best form which has yet been devised,but except as defined in the claims the invention is not limited to thespecific constructions and arrangements of parts of this machine but maybe otherwise embodied without departing from the spirit thereof.

The various features of the present invention will be clearly understoodfrom the following description taken in connection with the accompanyingdrawings, in which Figure 1 is a view in side elevation of a rollingpressure sole pressing machine embodying the same in their preferredform; Fig. 2 is an edge view of one of the jack supporting arms; Fig. 3is a sectional plan view of the mechanism illustrated in the lowerportion of Fig. 1 with the jack supporting arms omitted; Fig. 4 is arear view of the mechanism illustrated in the lower portion of Fig. 1;Fig. 5 is a sectional view looking in the opposite direction from Fig. 4illustrating the mechanism at the lower rear portion of the machine withthe jack supporting arms omitted; Fig. 6 is a view in side elevation ofone of the jack supporting arms detached from the machine; and Figs. 7and 8 are detail views illustrating the construction and mode ofoperation of one of the latches which are controlled by the operator andwhich hold the clutches which connect the jacks and forms to the drivingshaft out of operation.

Described in general terms the machine illustrated in the drawingscomprises two pivotally mounted shoe supporting jacks and two pivotallymounted cooperating sole pressing forms, the jacks and forms beingarranged substantially as in the machine disclosed in the patent toTripp No. 296,486 and acting when oscillated to subject the soles ofshoes supported upon the jacks to a rolling ressure. Each jack and itscooperating form is positively actuated from a main driving shaft bymeans of a worm shaft meshing with toothed segments upon the jack andform carrying arms and connected by bevel gears with the driving shaftsubstantially as in the machine of the Tripp patent.

In the patented machine the jacks and forms are permanently connected tothe driving shaft so that both jacks and their cooperating forms areactuated simultaneously, one jack and form being moved inwardly tosubject the sole of the shoe supported upon .ments are continued as longas the operator the ack to pressure, and the other jack and itscooperatlng form being moved outwardly to bring the jack into a positionto allow a shoe to be removed therefrom and another shoe to be placedthereon, which position is termed the position of presentation. Alsoeach jack and form is stopped when the jack is in a position ofpresentation and also when the jack is in its extreme inward position ofpressure the driving shaft beingautomatically stopped at the end of themovement of "a ack and form in each direction and being started so as torotate alternately in opposite directions by the o erator.

In the machine i ustrated in the drawings means are provided forconnectingeach jack and its cooperating form to the driving shaft andfor disconnecting them therefrom so that one ack and form remain at restat the front of the machine with the jack in a position of presentationto allow for the removal of a shoe therefrom and the placing of anothershoe thereon while the other jack and form are being actuated to levelthe sole of a shoe. The jack and form which are being actuated are onlystopped when the jack is in a position of presentation, mechanismactuated by the movement of the jack being provided for automaticallyreversing the direction of rotation of the main drivin shaft. Thismechanism is under the contro of the o erator and is so arranged thatafter one of tie jacks and forms have been connected to the drivingshaft the jack and form are moved toward the rear of the machine tosubject the sole of a shoe upon the jack to a 'rolling pressure and arethen moved forward and backward through a less distance to subject thesole of the shoe to a number of rolling pressures. These shorterpressing movedesires and then the jack and form are re turned to thefront of the machine and are disconnected from the driving shaft when.the jack reaches the position of presentation.

The jacks and their cooperating forms are connected to the driving shaftalternately,

means being provided whereby the movement of one jack to a position ofpresentation at the front of the machine disconnects that jack and itscooperating form from the driving shaft and releases the means forconnecting the other jack and form to the driving shaft. Also means areprovided whereby the means for connecting one ack and form to thedrivingshaft is held out of operation 'while the other jack and form arein operation.

The starting and stopping of the machine is controlled by the operatorby means of a foot treadle, but theorder in which the acks and forms areconnected to the driving shaft and the movements of the jacks and formswhen in operation are controlled automatioally by the movements of thejacks. In

order to stop the machine at any point in its operation, means under thecontrol of the operator is provided by which the operator can disconnectthe ack and form in operation from the driving shaft at any point intheir movement.

Referring now to the drawings, 1 indicates two form carrying armspivotally mounted at 2 in the upper portion of the machine frame, and 3mdicates two jack carrying arms pivotally mounted at 4 in the machineframe beneath the arms 1. The jacks and forms mounted upon these armsare of any usual or suitable construction and the arrangemerit of thearms is such that when the arms are oscillated the soles of shoessupported upon the jacks are subjected to a rolling pressure. To thearms 1 are secured worm segments 5 and to the arms 3 are secured wormsegments 6. These worm segments mesh with worms 7 and 8 secured tovertical shafts 9 ournaled in bearings in the rear ortion of the machineframe. At their ower ends the shafts 9 are provided with bevel gears 10which mesh with oppositely disposed bevel gears 11 upon the drivingshaft 12. The above described connections between the jack and formcarrying arms and the driving shaft are such that a rotation of theshaft 12 alternately in opposite directions imparts inward and outwardoscillating movements to the jacks and forms supported by the arms, theconstruction being the same as in the machine disclosed in the patent toTripp above referred to. The bevel gears 11 are, however, looselymounted u on the driving shaft 12 instead of being rigidly connectedthereto as in the machine of the Tripp patent and are connected theretoas will be hereinafter described so that the jacks and their cooperatingforms are operated alternately, one jack and form remaining at rest atthe front of the machine while the other jack and form are beingactuated to press the sole of a shoe.

The means for rotating the driving shaft 12 in opposite directions arethe same as in the machine of the Tripp patent and comprise twooppositely driven pulleys 13 and 14 mounted to rotate loosely and slidelongitudinally upon the driving shaft, and two friction clutch disks 15and 16 secured to the driving shaft and arranged to cooperate withfriction faces on the pulleys 13 and 14. The pulleys 13 and 1e are movedalternately into engagement with the friction clutch disks 15 and 16 .bymeans of a shipper rod 17 provided with arms engaging grooved collars onthe hubs of the pulleys and which is moved longitudinally in oppositedirections by mechanism which is actuated from the arm 3 of the jackwhich is in operation.

The mechanismifor actuating the shipper rod will be clearlyunderstoodfrom an inspec tion of Figs. 1, 3 and 5. Referring to these;

p the shipper rod 17.

figures and more particularly to Fig. 5, 18 and 19 indicate two camslides mounted to reciprocate vertically in guideways in the machineframe and to engage respectively rolls 20 and 21 mounted on blockssecured to The adjacent faces of the upper ends of the cam slides 18 and19 are provided with rack teeth which mesh with the teeth of a pinion 22mounted to retate upon a stud fixed in the frame of the machine betweenthe upper ends of the slides. The cam slides are thus connected togetherso as to move simultaneously in opposite directions, the upward movementof one slide producing a downward movement of the other slide. Thearrangement of the cam faces on the cam slides with relation to therolls 20 and 21 is such that an upward movement of one slide and acorresponding downward movement of the other slide moves the shipper rod17 longitudinally in one direction or the other and thereby reverses thedirection of rotation of the driving shaft by disconnecting one of thedriving pulleys 13 and 14 from the driving shaft and connecting theother pulley thereto.

The slides 18 and 19 are actuated during the operation of the machine byprojections on the arm 3 of the jack which is in operation and to thisend each slide is provided with a projecting lug 23, one of which isarranged to be engaged by the projections on one of the jack supportingarms 3 and the other to be engaged by the projections on the other jacksupporting arm. The projections on one of-the jack supporting arms whichengage the lug 23 of the slide 19 are indicated at 24 and 25 (see moreparticularly Figs. 2-and 6). These lugs and certain other parts carriedby the jack supporting arm 3 illustrated in Figs. 2 and 3 are duplicatedon the other jack supporting arm but are omitted from Fig. 1 in whichthe other arm is shown to avoid confusing the drawings. The projection24 engages the lug 23 of the'slide 19- when the jack is in its extremeinward position and actuates the slides 18 and 19 to reverse thedirection of rotation of the driving shaft to cause the ack to be movedtowards the front of the machine. When the jack is in its extreme inwardposition the toe portion of the shoe is being subjected to pressure. Itwill be evident that a shorter inward movement is required for a shoe ofa small size than fora shoe of a large size and in order to adjust theextent of theinward movement to suit shoes of varying sizes theprojection 24 is adjustably secured to the arm 3 by means of a boltpassing through a slot in the projection.

The projection 25 is arranged to engage the lug 23 during the outwardmovement of the jack and before the jack reaches its position ofpresentation at the front of the machine so that when the jack and. itscoperating form are connected to the driving shaft they are iven aseries of backward and forward oscil ating'movements sufficient inextent to press the sole of the shoe supported u on the jack but notsufficient to separate tiie jack and form and bring the jack into aposition of presentation. These relatively short oscillating movementsare continued so long as the projection 25 is allowed to engage the lug23 during the outward movement of the jack. In order to allow the jackto return to its position of presentation at the front of the machine,means under the control of the operator are provided for preventing theengagement of the projection 25 with the lug 23. To this end theprojection 25 is pivotally mounted upon the arm 3 and is normally heldin a position to engage the lug 23 by means of a spring 26 as is clearlyshown in Fig.2.

A cam plate 27 is provided (see more articularly Fig.5) which is securedto a side 28 mounted upon a vertical 'uideway of the machine frame. Thiscam p iate is provided with cam surfaces on its opposite edges which arelocated in the path of movement of the projections 25 on thejacksupporting arms 3. The normal position of the cam plate while one of thejacks and its cooperating form are in operation is that illustrated inFig. 5 and when the cam plate is in this position it will be seen thatthe projection 25 of the jack supporting arm which is in operation ridesover one of the cam surfaces of the cam plate and is then projected byits spring into a position to engage one of the lugs 23. The cam plate27 can, however, be raised into a position in which one of its camsurfaces forms a continuation of the outer surface of the lug 23 whichwould otherwise be engaged by the projection 25 of the jacksupportingarm in operation and when in this position the projection 2-5 is causedto ride over the lug 23 without engaging therewith and the jack isallowed to return to its position of presentation at the front of themachine. The cam plate 27 is moved into a position to prevent theprojection 25 from en gaging the lug 23 by means of a treadle lever 29connected by means of a link 30 to one end of a lever 31 pivoted uponthe frame of the machine and engaging at its other end with the slide28, the arrangement being such that the depression of the treadlelever29 by the operator raises the slide28 and the cam plate 27 securedthereto.

As has been stated the bevel gears 11' are mounted loosely upon the maindriving shaft 12 and areconnected thereto alternately so 1 that one jackand form remains at rest at the front of the machine with the jack in aposition of presentation while the other jack and form are beingactuated to level the sole of a shoe. The bevel gears are connected tothe shaft by means of clutches each of which comprises a recessed block32 secured to the driving shaft upon one side of a gear 11 and a groovedcollar 33 uponthe other side of the gear mounted loosely upon a sleeveintegral with the gear so as to be capable of sliding longitudinallythereon and being provided with pins passing through holes in the gearand arranged to engage the recesses in the block 32. Each grooved collar33 is engaged by the lower end of a lever arm 34 ivotally mounted u on astud 35 secured in t e frame of the mac ine. An arm 36 extendsdownwardly from the hub of each lever arm 34 and the two arms 36 areconnected by means of a coiled sprin 37, the construction being suchthat the spring tends to move the arms 34 in a direction to clutch thebevel gears 11 to the driving shaft.

The movements of the arms 34 are controlled by the jack supporting arms3, means being provided whereby one of the arms 34 is actuated todisconnect from the driving shaft the bevel gear 11 from which the jackand form in operation are actuated when the jack is returned to itsposition of presentation and whereby the other arm 34 is prevented frombeing moved to connect the other bevel gear 11 to the driving shaftuntil the jack and form in operation have been brought to rest at thefront of the machine. The means illustrated in the drawings foraccomplishing these results will be clearly understood from aninspection of Figs. 1, 2, 3 and 5. Referring to these figures 38indicates two 'disks upon the forward end of two short horizontal shaftsj ournaled in the frame of the machine, a disk being located in closeproximity to each of the arms 34. Each of these disks is provided with apin 39 mounted to slide freely in a guideway extending diametricallythrough the disk and with a'pin 40 projecting from the face of the disk.The pins 40 are arranged to be engaged by projections 41 on the jacksupportingarms 3 and the pins 39 are arranged to be engaged by camplates 42 secured to the jack supporting arms 3, the construction andarrangement being such that when the jack and form which are inoperation are moved to bring the jack into its position of presentationat the front of the machine the projection 41 on the jack supporting armengages a pin 40 of a disk 38 and turns the disk so as to-cause oneendof the pin 39 of the disk to bear against a plate 43 on one of the arms34 and to bring the other end of the pin 39 into the path of movement ofthe cam plate 42 and thereafter the cam plate 42 forces the pin endwiseagainst the plate 43 of the arm 34 and moves the arm to disconnect fromthe driving shaft the bevel gear 11 from which the jack and form inoperation were actuated. Upon the rear ends of the shafts of the disks38 are secured crank disks 44 which are connected by a link.

above description that when one jackand its cooperating form are inoperation the other jack and form are held out of operation by theengagement of the cam plate 42 of the jack supporting arm which is atrest with a pin 39 and that the disk carrying this pin is moved to allowthe jack and form which have been at rest to be thrown into operationwhen the jack and form which have been in operation are brought to restin their initial position at the front of the machine.

In order to prevent the jack and form which are at rest from beingthrown into operation while the other jack and form are being actuated,in case the disks 38 are accidentally rotated, a locking rod 46 ispivotally connected to each arm 34 and is mounted to slidelongitudinally in bearings in the frame of the machine. Each of theserods is provided with a block 47 secured thereto upon which is mounted aroll 48 arranged to bear against the inner surface of one of the wormsegments 6 secured to the jack supporting arms 3. When the jacks are intheir position of presentation at the front of the machine the rolls 48are out of engagement with the inner surfaces of the worm segments 6 sothat when the jacks aregin this position the locking rods do not preventthe movement of either arm 34 to connect one of the bevel gears 11 tothe driving shaftl As soon, however, as one of the jacks an'fzl forms isthrown into operation one of the rolls 48 is engaged by the innersurface of the worm segment 6 of the jack supporting arm and thereby theother jack and its cooperating form are prevented from being thrown intooperation until the jack and form which are in operation have beenreturned to their initial position at the front of the machine.

If no means other than those hereinbefore described were provided forcontrolling the movements of the lever arms 34, one jack and itscooperating form would be thrown into operation as soon as the otherjack and form were returned to their initial position at the front ofthe machine, so that the two jacks with their cooperating forms would beoperated alternately so long as power was applied to the main drivingshaft. The machine illustrated in the drawings is, however, providedwith means under the control of the operator for controlling themovements of the lever arms 34 so that the jack and form which have beenat rest are not thrown into operation until the operator desires. Thismeans for controlling the movements of the lever arms 34 comprises twolatches 49 pivotally mounted upon a hori zontal rock shaft 50 journaledin bearings at the rear of the machine frame and arranged to swing intoa position to engage the arms 36 and hold the lever arms 34 in theposition in which the bevel gears 11 are disconnected from the drivingshaft. The construction and mode of operation of these latches will beclearly understood from an inspection of Figs. 1, 4, 7 and 8. Each ofthe latches 49 is acted upon by a spring 51 coiled around the rock shaft50 and having one end in engagement with the frame of the machine andthe other end in engagement with the latch, the arrangement of thesprings being such as to tend to force the latches into a position toengage the arms 36. Each latch is provided with a laterally projectingpin 52 which is arranged to be engaged by a pin 53 projecting from acollar fast on the rock shaft. The rock shaft 50 is provided with an arm54 which is connected by a link 55 to an arm projecting upwardly fromthe treadle lever 29. The arrangement of the pins 52 and 53 and theconnections between the treadle lever 29 and the rock shaft 50 are suchthat when the treadle lever is raised the shaft 50 is rocked so as tobring the pins 53 into engagement with the pins 52 and move the latches49 against the tension of springs 51 into a position in which they areout of engagement with the arms 36, and when the treadle lever isdepressed the latches 49 are pressed toward the arms 36 by means of thesprings 51. When, therefore, the treadle lever 29 is depressed by theoperator in order to raise the cam plate 27 so as to cause the jack andform which are in operation to return to their initial position at thefront of the machine, the latches 49 are allowed to move towards thearms 36 under the force of the springs 51, one latch moving immediatelyinto a position to engage one of the arms .36 so as to prevent the jackand form which are at rest from being thrown into operation, and theother latch being pressed against the other arm 36 until the jack andform which have been in operation are disconnected from the drivingshaft, and then moving into engagement with the arm. In order to throwthe jack and form which have been at rest into operation the treadlelever 29 is allowed to rise, thereby removing the latches 49 fromengagement with the arms 36. When both jacks and their cooperating formsare at rest at the front of the machine, the treadle lever 29 is helddepressed by a locking lever 56 pivoted upon the frame of. the machineand provided at its upper end with a handle by means of which it can bereadily actuated byv the operator to release the treadle lever. Thetreadle lever is depressed by the operator and is raised when releasedfrom the locking lever 56 by means of a coiled spring 57 connected atone end to the treadle lever and at the other end to the frame of themachine.

It is desirable in rolling pressure sole pressing machines that means beprovided whereby the jack and form which are in operation can be stoppedat any point in their movement as, for instance, to prevent crushing thehand of an operator accidentally caught between a jack and form. To thisend the machine illustrated in the drawings is provided with a cam 58arranged to bear against the side of one of the lever arms 34 andsecured to a shaft 59 j ournaled at its inner end in a block 60 securedto the rod 46 which is connected to the other lever arm 34 and journaledat its outer end in the frame of the machine (see Figs. 1, 3 and 5). Theouter end of the shaft 59 is bent upwardly to form a handle by means ofwhich the shaft may be rocked by theoperator. The normal position of thecam 58 is that illustrated in Fig. 5. T/Vhen it is desired to stop thejack and form which are in operation the shaft 59 is rocked by theoperator and the cam 58 is brought into engagement with the arm 34adjacent thereto. If this arm is in the position illustrated in Fig. 5it is moved to disconnect the bevel gear 11 to which it is connectedfrom the drivin shaft. If this bevel gear is disconnected from thedriving shaft and the bevel gear on the opposite side of the machine isconnected thereto a rotation of the shaft 59 brings the cam 58 intoengagement with the arm 34 as before and the cam acts to move the innerend of the shaft 59 laterally and through the rod 46 to move the otherarm 34 so as to disconnect the bevel gear on the other side of themachine from the driving shaft.

The operation of the machine above described 18 as follows :Startingwith the parts in the position illustrated in the drawings in which thetreadle lever 29 is in its raised position and the jack and form uponthe right-hand side of the machine as viewed from the front of themachine are in operation, the jack and form move inwardly until theprojection 24 upon the jack supporting arm 3 engages the lug 23 of thecam slide 19 when the cam slide 19 is depressed and the cam slide 18 israised, thereby shifting the shipper rod 17 and reversing the directionof rotation of the driving shaft. The jack and form move outwardly untilthe projection 25 engages the lug 23 of the cam slide 19 and-actuatesthe cam slides 19 and 18 to again reverse the direction of rotation ofthe driving shaft. These inward and outward movements of the jack andform are sufiicient in extent to subject all portions of the sole of ashoe upon the jack to pressure but are not sufficient to return the jackand form to their initial position at the front of the machine. Afterthe shoe has been subjected to the desired number of pressing erations Ithe o erator depresses the treadle ever 2.9,

there y, through the link 30 and lever 31, raising the cam plate 27.VVlule the cam plate is in its raised position the jack and form aremoved outwardly and as the projection reaches the cam plate 27 it iscaused to ride over the cam surface of the plate and over the projection23 of the slide 19 without engaging the same. The jack and form continuetheir outward movement,

This rotation of the disk 38 illustrated at the right-hand side of Fig.5 rotates the disk 38 illustrated at the left-hand side of the figureinto a position in which the pin- 39 mounted in the disk is out ofengagement with the arm 34 adjacent thereto. During the backward andforward movements of the ack and form at the right-hand side of themachine, the jack and form at the lefthand side of the machine are helddisconnected from the driving shaft by the pin 39 of the disk 38 at theleft-hand side of Fig. 5 and by the engagement of a roll 48 on one ofthe locking rods 46 with the inner surface of the worm segment 6attached to the jack sup porting arm in operation. After the jack andform which have been in operation are disconnected from the drivingshaft as above described, both jacks and forms remain at rest until thetreadle lever 29 is allowed to rise, both lever arms 34 being held in aosition in which the bevel gears 11 are isconnected from the drivingshaft by the engagement vith the arms 36 of the latches 49.

When the treadle lever 29-is allowed to rise 7 the latches 49 are movedout of engagement with the arms 36 and the arm 34 illustrated at theleft-hand side of Fig. 5 is allowed to move into a position in which thebevel gear 11 on the left-hand side of the machine is connected to thedriving shaft. The jack and form at the left-hand side of the machineare thus throw 11 into operation and are actuated to level the sole of ashoe and are returned to their initial position at the front ofthe-machine and brought to rest, when the treadle 24 is again depressedby the operator, the operation being the same as that of the ack andform at the right of the machine above described. The driving shaft 12rotates continuously in one direction or the other so long as power isapplied thereto and the two jacks and their cooperating forms areconnected thereto and disconnected other of the lever arms 34 moved ashas been described to disconnect one of the bevel gears 11 from thedriving shaft.
